java.net.socketpermission on WebCenter Content (UCM) Applets

After the one of the last updates of my local JRE I couln't connect to the UCM Applets of the client throught the proxy connection.

This error appears:

To solve this issue, go to your "java.policy" file, mine is under this path:

C:\Program Files (x86)\Java\jre7\lib\security\java.policy

Modify your file and add this line at the end of the file:

permission java.net.SocketPermission "*", "connect,accept,resolve"; 

After that modification, close all your browsers and retry to open the Applet.
